    The acceleration vector field developed in a beam-like elastic structure is sampled over the space–time domain by a tri-axial accelerometer relocated over the beam surface while triggered by another mono-axial accelerometer fixed in space to attain synchronism. This technique leads to structure-geometry consistent spatio-temporal measurements of coupled structural dynamics. T1 - Optimal sensor placement of large flexible space structures.

Efficient placement of structural dynamics sensors on the space station (SuDoc NAS ) [Janet A. Lepanto] on *FREE* shipping on qualifying offers. The placement of structural dynamics sensors on the space station is a particularly challenging problem because the station will not be deployed in a single mission.

Given that the build-up sequence and the final configuration for the space station are currently undetermined, a procedure for sensor placement was developed using the assembly flights 1 to 7 of the rephased dual keel space station.

[Janet A Lepanto; G Dudley Shepard; United States. National Aeronautics and Space Administration.]. The placement of structural dynamics sensors on the space station is a particularly challenging problem because the station will not be deployed in a single mission.

The build-up sequence of several assembly flights means that it is actually a series of space stations that must be instrumented, not just a final configuration. The placement of structural dynamics sensors on the space station is a particularly challenging problem because the station will not be deployed in a single mission.

Dudley Shepard and Janet A. Lepanto. Most recently the problem of optimal sensor placement for state estimation and joint state-input estimation has been treated by Weickgenannt at al., van den Linder et al.

and Zhang and Wang. In an optimal sensor location strategy was developed for an active shell structure. The approach was based on a dual-objective optimization, namely minimizing the number of sensors and a measure Cited by: 9.

Vehicle structural modes reside at the low-frequency end of the vibratory portion of the acceleration spectrum. These vibrations fall within the frequency range from about hertz to about 5 hertz. These vibrations arise from the excitation of natural frequencies associated with large components of the space station structure, such as.

A real-time computer-hardware simulation for the investigation of space station dynamics and control problems is described. The simulation utilizes full-scale control moment gyro (CMG) hardware mounted on a moving base simulator, a manual console, and a Control Data (CDC) digital computer to represent a space station and its control system.

Unlike traditional sensor placement approaches, in which these two types of sensors are often designed separately to monitor structural deformations and displacements respectively, the integrated design procedure presented in this study treats the sensor system as a whole.

The optimum location of the sensors is a critical issue of any successful Structural Health Monitoring System. Sensor optimization problems encompass mainly three areas of interest: system.

The objective of optimal sensor placement (OSP) is to obtain a sensor layout that gives as much information of the dynamic system as possible in structural health monitoring (SHM).

An example is shown in Fig. 4 where the optimal sensor locations for a test on a prototype for the space-station return vehicle are derived from a FE model. Fig. 4: FE-based sensor grid definition for a space structure Test Instrumentation.

Structural vibrations propagate via mechanical linkage and transmission. While the frequency of these disturbances may be registered the same throughout the space station, their amplitude is a function of location. Structural mode vibrations tend to be low amplitude during crew sleep periods relative to.

"Introduction to Space Dynamics" by William Tyrrell Thomson Overall, this is a classic and essential book for those serious about astrodynamics and understanding space systems. The text is a great introduction to a broad set of categories in space dynamics including both rocket and satellite s: Sensors and Instrumentation, Aircraft/Aerospace and Energy Harvesting, Volume 7: Proceedings of the 38th IMAC, A Conference and Exposition on Structural Dynamics,the Available Formats: Hardcover eBook.

This book, edited by the European Space Policy Institute, is the first international publication, following UNISPACE+50, to. Zhou 14 used a genetic algorithm to apply the energy‐based sensor placement theory criterion to a space grid structure and optimized the placement of sensors in the space grid structure.

Based on the model polycondensation method, Yi et al 15 optimized the Guangzhou New TV Tower accelerometer sensor placement.Figure The finite-element model of the International Space Station structure. Based on this definition, we derive many interesting properties of structures and their controllers later in this book.

The above conditions are somehow restrictive, and introduced to justify the mathematical approach used in this book.Janet A.
